Let us see some negative effects of volcanoes:
volcano factEruptions occurring close to human settlements may spill and destroy lives and property. People often have to be evacuated.
Example: Chaparrastique volcano in El Salvador started erupting on 29 Dec, 2013. Anyone living within 2 miles of the volcano is evacuated.

volcano factAsh discharged very high into the stratosphere can have negative consequences on the ozone layer. Read more about that here.
volcano factLandscapes and natural sceneries can be destroyed.
volcano factAsh and mud can mix with rain and melting snow, forming lahars. Lahars are mudflows flowing at very fast pace.
Some positive effects of volcanoes include:
volcano factDifferent types of erupting volcanoes provide extraordinary scenery, so beautiful and natural that they attract tourists to the area, bringing in some economic value.
volcano factPlaces close to volcanic activities tend to have higher potential for geothermal energy, which can be an advantage to the towns and cities.
volcano factSome ash and lava breakdown become soils that are rich in nutrients, and become good areas for crop planting activities.
DID YOU KNOW:
El Salvador has about 20 volcanoes, and the area falls within the larger Pacific Ring of Fire (an area know for its frequent tectonic movements and earth activity). This Ring of Fire is the home of 75% of the worlds

There is your answer
Explanation:
If the ashfall is really heavy it can make it impossible to breathe. Lava flows are almost always too slow to run over people, but they can certainly run over houses, roads, and any other structures. Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes.
